Harrington and Richardson (H&R) Firearms:
There is not a lot of information available about individual models of firearms that Harrington and Richardson manufactured. Harrington and Richardson manufactured reliable utilitarian low cost firearms from 1874 when they were founded, until 1986 when they ceased production, the H&R trademark was also utilized by a new company (H&R 1871, Inc.). H&R firearms were solid and durable, but plain and cheap. Even in nice condition, there is about zero collector interest in old H&R firearms. Values are well under $100, and usually under $50.00. If there is any sentimental value we recommend that they be kept as a family heirloom from the days when people owned and used guns safely and responsibly without the need for draconian government supervision to make it "safe for our kids". The exceptions to this rule are the H&R M1 Garands and H&R U.S. Model 1873 rifles. H&R made the M1 in the 1950's and these are highly collectible. They also made a replica Model 1873 rifle, which is collectible.

*Note - We would strongly advise that any old firearm should be checked by a competent gunsmith both for safety and to verify the caliber before an attempts is made to fire it.
